1906 Earthquakes Report

Earthquakes. They shake buildings, they wobble structures, they dismantle even the most stable construction. They leave people without homes, destroy possessions. The San Francisco earthquake in 1906 left at least half of the population homeless.

Question Set 7 A) What types of methods and tools are used to measure, document and analyze ancient fault activity along the San Andreas Fault and its associated faults? For example, how do geologists determine how long a fault has been active, how often it ruptures, its relative offset motion, and how much offset? Note that the term "ancient" means fault activity that occurred thousands to millions of years ago - long before seismologists were around. Modified Mercalli Intensity Scale: Measures the intensity of an earthquake Richter Scale: Used to measure the magnitude of an earthquake (Tarbuck, 2013)

The two plates that moved were the North American tectonic plate and the Pacific tectonic plate. The plates moved about 15 feet, this is huge because the average movement of tectonic plates during an earthquake is only 2 inches. The earthquake only lasted a minute but it quickly destroyed the city. The earthquake

Personal interview. 11 Sep. 2017. Montgomery, David R. “Effects of the Loma Prieta Earthquake, October 17, 1989, San Francisco Bay Area.” Effects of the Loma Prieta Earthquake, October 17, 1989, San Francisco Bay Area, University of California, Berkeley, 2010, www.johnmartin.com/earthquakes. Web.

The text asserts that there were no sweeping fires to blame, only the earthquake. This event led to the first major legislative initiative in California to recognize seismic issues: the Field Act of 1933. Steinberg contends that although this was a step in the right direction, seismic enlightenment was still difficult. The author notes that regardless of awareness, many built in areas vulnerable to harmful seismic activity (i.e. near fault lines). The author also states that California is not the only area prone to earthquakes and that typically the poor suffer more from these events wherever they happen.

San Francisco, California has experienced fourteen earthquakes above a magnitude above 5.1 since 1836. The earthquakes of 1865 and 1906 both brought on varying forms of destruction. Twain, writing about the earthquake of 1865, found amusement and humor in the devastating event; while London only saw the destruction and loss in the earthquake of 1906. To inform and to entertain are, respectively, Jack London’s and Mark Twain’s purposes in writing about the two different earthquakes that struck San Francisco. Both writers experienced the earthquakes’ destruction first-hand, but had very different interpretations of it.

It was assigned a magnitude of 9.5 by the United States Geological Survey. It is referred to as the “Great Chilean Earthquake” and the “1960 Valdivia Earthquake.” Other earthquakes in recorded history may have been larger;however, this is the largest earthquake that has occurred since accurate estimates of magnitude became possible in the early 1900’s (“The Great Chilean Earthquake”). Earthquakes are very dangerous, and if you live in an earthquake bound area, you always need to be prepared for destruction. The San Andreas is 800 miles long and a myth about it is that one day half of California will break off into the ocean, some believe it, others

This is typically referred to as the Great San Francisco Earthquake.” The earthquake of 1906 was one of the biggest earthquakes in California history. It was measured at a magnitude of 7.8. That is a big earthquake. In the two eyewitness accounts “Comprehending the Calamity” by Emma Burke, and “Horrific wreck of

The article “Chances of Earthquake Hitting L.A. Area Soon: Like, for Sure” by Tia Ghose is about the probability of an earthquake in Los Angeles. The greater Los Angeles area has a 99.9 percent chance of having an earthquake of magnitude 5.0 or greater in the next two and a half years according to a study published september 30 in the journal Earth and Space Science. One fact I learned while reading this article is that there was a magnitude 5.1 earthquake that struck La Habra, California in 2014 that resulted in $12 million in damages. Another fact I learned while reading this article, is that there is an instrument called the Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR) that detects teeny shifts in the Earth's surface as

San Juan Bautista was named in honor of St John Baptist, also known as the mission of music because of the beautiful piano music that was played there. No one knew that San Juan Bautista mission was located in the San Andreas Fault, it became known after the mission was built. Even after it was known that the mission was located in a dangerous location because of the tremors, nobody did anything about it. In October of 1798, there was a huge shaking of the earth (earthquake), that caused huge cracks to the buildings, there were about five tremors per day but even then, the mission survived the quakes. The missionaries’ had to sleep outside for a whole month because of the shakings and even thought the shakes caused damages, the mission was never moved from its original

When was the first earthquake in North Carolina recorded? The first recorded earthquake was on March 8th, 1735 near Beth. Another one on February 21st, 1774 this one was quite noticeable speaking there were some reports from Winston Salem through Virginia. How do tsunamis form?

The problem is that scientists didn 't know how earthquakes and faults had anything to do with each other until after the San Francisco earthquake on April 17,1906. Since then scientist have move past that. Being able to predict earthquakes would benifits citizens and their cities tremendously! The issue is that they are simply educated guesses, nothing certain.

For example, one environmental impact of the event was according to “1960 VALDIVIA EARTHQUAKE, CHILE” by Asti Tobias and Chris Lee it is estimated that 40% of the homes in Valdivia were destroyed leaving 20,000 of its residents homeless. Some structures completely collapsed due to the lack of earthquake engineering in many of the buildings. Houses built on high elevation suffered less damage than the homes built in the lowlands because the lowlands received much more energy from the earthquake that the high land didn't receive. The city center of Valdivia was so destroyed that it was uninhabited until the 1990s, and the 2000s. (Tobias & Lee).

It is still impossible for scientists to predict when and where an earthquake will happen exactly although there is progress used to estimate the probability of future

1.2 Damages: • Because an earthquake is literally the quaking of the earth, you can imagine that anything on the surface that is near the shaking will shake as well. • Earthquakes have the same affect on land. Landslides and mudslides are common
